What is the correct orientation of the ignitor shield? Does it go between the ignitor gas source, or does the ignitor go between the shield and gas source?


There is no igniter shield that I am aware of outside of a grill to protect it from grease. I'm not sure what you have or are working on, but nothing should be between the igniter and gas supply. That could slow ignition, thus creating a build-up of gas before ignition and that's bad.
